中文摘要：

针对Pyrak-Nolte等人在计算多结构面的总透射系数时存在的问题,把非充填型结构面抽象为弹簧,用参数K/（Zω）讨论结构面刚度、频率和间距对应力波在多结构面间多次反射和透射的影响。研究结果表明：波形相关系数和透射系数随结构面参数变化具有相同的变化规律;结构面间距与波长之比存在一个临界值,当结构面间距与波长之比大于该临界值时,多重反射和透射对应力波传播过程影响很小,可以认为结构面间距对总透射系数没有影响;临界值与K/（Zω）有关,K/（Zω）增大,临界值减小。

英文摘要：

In view of the existing problem in calculating total transmission coefficient of multi-structural face by Pyrak-Nolte,influences of structural face stiffness,stress wave frequency and interval on multiple reflections and transmissions of stress wave in multi-structural face were studied with dimensionless quantity K/Zω,by simplifying non-filling structural face as spring.Results indicated that wave shape correlation coefficient and transmission coefficient varied with parameters of structural face following the same rule.There existed a critical value for the ratio of structural face interval and wave length.When this ratio was higher than the critical value,propagation process of stress wave was least affected.It is concluded that structural face interval has nothing to do with total transmission coefficient and the critical value is related with K/Zω,that is K/Zω increases as critical value decreases.
